STEAM-TURBIN E.

are 849,455.

parts, of simple and compact form, in which -'the utilization of steamis greatly augmented vision of a steam-turbine engine having asinand thewaste of the same reduced to a minimum.-

My invention consists in the provision of a ste-am turbine engine inwhich the wheel and the buckets on its periphery are formed, preferably,by casting, of a single piece of metal.

My invention further consists in the progle wheel formed with buckets onits periphcry in duplicate, each series of buckets being so constructedthat admission of steam to one set will revolve the wheelin an oppositedirection from that produced by the admission of steam to the otherseries of buckets on the same Wheel.

My invention, still further consists in the provision of a steam-turbineengine having two series of buckets oppositely situated upon theperiphery of its wheel and means for controlling the admission of steamto either of the series of buckets, as desired, and thereby operatingthe engine in either .direc tiop,

My invention still further consists in the.

provision of a steamturbine wheel with exhausts so constructed that thesteam will be readily exhausted after performing its designed workwithout any tendency to retard themovement of the wheel.

My'invention still further consists in the construction, combination,and arrangement of parts more fully described hereinafter andspecifically claimed.

In the accompanying drawings, which form a part of this specification,Figure 1 is a central vertical section view of my improved engine, takenlongitudinally of the shaft. Fig. 2 is a vertical sectional view of thesame. Tig. 3 is an end view of the bucket-wheel. Fi 4 is a detached viewof the slide-valves.

1, which, as shown, is made ofa single casting, the upper casing 2, andits base 3, which is likewise a single .casting, formed to receive thewheel 9 and also so constructed at its top as to permit of theattachment of the frame 4 of the slide-valve 5.. The sections 1 and 3are firmly bolted together, suitable packing being placed between theirabutting surfaces to prevent the escape of steam. Circular end plates 66 are bolted and suitably packed at the opposite ends of thewheel-opening in the frame 2. The head-plates 6 6 are provided withopenings and packing-boxes 7 for the passage of the shaft 8 ,which maybe supported by -'the packing-boxes or journaled lIl separatepillow-blocks attached to the base-plate. The wheel 9, which is suitablykeyed to and revolves with the shaft 8, consists of a single castingprovided with two parallel series of buckets 10 and 11 on its periphery.The

buckets 10 and 11 are alike in shape, being triangular, with a radialbottom 28 and-the inclined top 29, the bottom of the wheel forming oneof their sides and the circular end plate the other side. allel bucketsare oppositely arranged with reference to the shaft and frame of theengine, as shown in Fig. 3, and are staggered with reference to eachseries.

Inlet-ports 12 and 13 pass through the upperpart of the casing, andexhaust-ports 15 and 16 are formed on opposite sides of the casing aboveits center. A slide-valve 17 is attached to the upper part of thecasing, covering the inlet ports 12 and 13, the 0 ero ation of theslide-valve being controlled y a handle 17, passing through the sideofthe valve-frame in a proper packing-box, its 7 outer end beingattached to a pivoted looking lever 18. steam-boilers and the upper partof the slidevalve boxes by means of pipes 19 20 21, provided withthrottle-valves 22 23 24. The exhaust-ports 15 16 may be provided withsuitable connections to lead the exhaustroo steam to the open air or acondensing' chamber or, if desired, to a lowressure engine, backpressurebeingprevente by suitable valves.

As the wheel revolves another bucket of the same series will bebrought under the inlet-port 12 and receive the in gactof the steam inthe same manner and en in the revolution of the wheel. The

bucket-first. filled will now be opposite the exhaust-port and the steamwithin it will exhaust through the port. Each bucket willsuccessively'receive and exhaust its steam,

the shaft 8 to any" connected-machinery. In the case of-niarineenginesone' ormore wheels can be used to rotate the ropellershaft,.whichcanbe keyed directly to the When it is desiredto reverse the motion ofthe engine, steam is cut ofi from the series of buckets 10 and allowedto pass through the port 13 into the series of buckets 11, exhaustingthrough the port 16, andfiasthe series-of buckets 11 are arranged in adifferent direction from that of series 10 the wheel and the shaft willrotate in the opposite direction, or to the right.

, The slide-valve is intended to regulate the i the engine, so as amountof steainadmitted into the casing of to control the speed of the engine.Y

Having thus described myinvention, what I claim as new, and desire topatent, is'

In an elastic-fluid turbine, the combination of a casing having theinternal facings of its end walls finished smooth, a Wheelmounted-therein and mounted so as to have a Working fit within the endwalls, a plurality of sets of peripheral buckets arranged with theirfluid-impinging faces in opposite direc tions, a peripheral partitionbetween adjacent sets of buckets, the buckets of adjacent setsbing-disposed in staggered relation, a steam-chest for each set ofbuckets having theirfluid-impinging surfaces extending in the samedirection, a nozzle for each set of buckets communicating with eachchest, a

slide-valve in each chest for controlling the flow-of motive fluidthrough the nozzle thereof, lever and latch mechanisms for actuating thevalves inde endently, a branched supplypipe connecte with thesteam-chests, and throttle-valves in the .-pipes for controlling thesupply of fluid to the chest independently. In testimony whereof I havesigned my name to this specification in the presence of the twosubscribing witnesses.
